Uba Tuba water spots

I have been following your forums for some time now and I recently had Uba Tuba Gold installed in my kitchen. The installers did put sealant on it however and I am developing water spots near my faucets/soap dispenser. Since Uba Tuba does not apparently need sealant I got a stripper and took off the sealant just a small area around the sink to see if it was etchings on the sealant that were causing my problem. However, they are still there. Suggestions? Did I not get all of the sealer off? Thanks for the help- am still wondering if I should just strip the whole thing or not.
